PID temperature controllers for coffee

What's a PID?

PID stands for Proportional-Integral-Derivative.

A PID controller uses a algorithm to determine the best way to control a process. 
They are used in a wide range of industrial applications but in our case, it usually controls temperature 

A traditional espresso machine uses a thermostat which once it hits a desired temperature turns off the heating element.

Below is a example of a  Arduino-based PID temperature controller for a La Pavoni espresso machine.
These old machines don't have thermostats. Temp surfing is their forte.
